Costco

Costco sells Kirkland Signature and other food brands and also operates meat-processing plants in Tracy, California, and Morris, Illinois.

About: Costco’s May 2023 publication described its Tracy and Morris plants making ground beef, patties and other meat products.
Sourcing: Costco sells products from distinct U.S., Australian, New Zealand and Japanese meat programs, with origin and raising claims varying by product.
Practices: Costco’s 2025 report permits veterinary-supervised antibiotics for disease prevention, control and treatment in meat production.
Practices: Its January 2026 North American welfare policy requires annual slaughter audits, while farm-audit frequency varies and overall audit coverage is incomplete.
Practices: Costco’s September 2025 ground-meat supplier requirements call for finished ground beef to be held until E. coli O157:H7 test results are negative.
